Corina Jo Castillo pleaded guilty to voluntary manslaughter with a sentencing enhancement for using a deadly weapon and was immediately sentenced to six years in prison, according to Deputy District Attorney Howard Gundy.

Orange County Superior Court Judge Robert Fitzgerald offered the plea deal to Castillo, who was arrested in June 2010.

She was initially charged with murder, but the charge was reduced to voluntary manslaughter based on further investigation that revealed Castillo and her 28-year-old boyfriend, Jesse James Foster, had a troubled relationship that included physical fights and drug use, the prosecutor said.

A message left with Castillo’s attorney, Orange County Public Defender Frank Bittar, was not immediately returned.

Castillo and Foster were under the influence of narcotics when they got into an argument on June 17, 2010, in their apartment at 2215 W. Broadway, Gundy said.

“During mutual combat, she took a kitchen knife and stabbed him in the back,” he said.

Foster left the apartment and stumbled down a flight of stairs before collapsing, Gundy said. Castillo ran away as neighbors called police.

She got away with murder just because she’s a woman and she used the “abuse excuse” defense, something that is not available to men. Had it been her boyfriend killing her, he would not have the option to plead guilty to manslaughter and he would have gotten the death penalty. Women simply don’t believe in equal responsibility.

You don’t know the woman. She was tortured by him almost every day until she finally knew he was going to kill her. I’m not saying that what she did was justified – but she has to get some credit for finally trying to defend herself.
